Two streets running along the river Arno are named after mathematicians. They also possess
a common junction. These are Lung'Arno
Fibonacci
and Lung'Arno
Galileo
Galilei. The word "Lung'Arno" means "along the river Arno". Due to the fact that
there are no houses situated in the street named after Fibonacci (Leonardo Pisano) no
street-sign is installed.
This is the only reason why above only the street-sign is presented which shows G. Galilei's
name.
